La v\u00e1lvula de alivio\/sostenedora de presi\u00f3n\u00a0<\/span>modelo 730<\/strong> es una v\u00e1lvula de control de operaci\u00f3n hidr\u00e1ulica, accionada por diafragma, que puede realizar cualquiera de las dos funciones. Intercalada en la l\u00ednea, sostiene una presi\u00f3n m\u00ednima predeterminada aguas arriba (retropresi\u00f3n), sin que le afecten las fluctuaciones de caudal o de presi\u00f3n aguas abajo. Si se instala como v\u00e1lvula de circulaci\u00f3n, alivia las presiones excesivas en la l\u00ednea, superiores a la m\u00e1xima predeterminada.<\/span><\/p>\n

Caracter\u00edsticas y ventajas<\/strong><\/p>\n

    \n
  • Accionada por la presi\u00f3n en la l\u00ednea \u2013 Operaci\u00f3n independiente<\/li>\n
  • Disco de cierre balanceado \u2013 Alta capacidad de alivio<\/li>\n
  • \u00a0<\/span>Mantenimiento sencillo en l\u00ednea<\/li>\n
  • C\u00e1mara doble\n
      \n
    • Reacci\u00f3n moderada de la v\u00e1lvula<\/li>\n
    • \u00a0<\/span>Diafragma protegido<\/li>\n<\/ul>\n<\/li>\n
    • Dise\u00f1o flexible \u2013 Permite incorporar funciones adicionales<\/li>\n
    • Variedad de accesorios \u2013 Perfecta adaptaci\u00f3n<\/li>\n
    • En “Y” o angular, cuerpo ancho \u2013 M\u00ednima p\u00e9rdida de presi\u00f3n<\/li>\n
    • Flujo semirrecto, no turbulento<\/li>\n
    • Asiento elevado de acero inoxidable \u2013 Resistencia a los da\u00f1os por cavitaci\u00f3n<\/li>\n
    • \u00a0<\/span>Cavidad libre de obst\u00e1culos \u2013 Absoluta confiabilidad<\/li>\n
    • Tap\u00f3n regulador V-Port \u2013 estabilidad con bajos caudales”<\/li>\n<\/ul>\n

      Aplicaciones t\u00edpicas<\/strong>
      \nProtecci\u00f3n de la bomba contra sobrecarga y cavitaci\u00f3n<\/strong>
      \nLa v\u00e1lvula Modelo 730 sostiene la presi\u00f3n de descarga de la bomba para impedir la sobrecarga de la bomba y los da\u00f1os por cavitaci\u00f3n provocados por una demanda excesiva. Al conectar la l\u00ednea sensora del piloto a la succi\u00f3n de la bomba, la v\u00e1lvula Modelo 730 se transforma en el Modelo 730R, sostenedora de la presi\u00f3n de succi\u00f3n de la bomba. Si el r\u00e9gimen de presiones de succi\u00f3n es variable, se requiere la v\u00e1lvula Modelo 736 para limitar el caudal de la bomba mediante el mantenimiento de la presi\u00f3n diferencial.<\/span><\/p>\n<\/div><\/div><\/div><\/div><\/div><\/div><\/section>\n","protected":false},"excerpt":{"rendered":"
